Abstract
Abstract A polymeric flexible hose construction and method of making same are provided wherein such hose construction comprises a tubular wall defining a main longitudinally extending passage for conveying a fluid therethrough and a second wall adjoining the tubular wall and defining a second longitudinally extending passage for an electrical conductor with the second wall having a wall portion common with the tubular wall.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
99 words
A polymeric flexible hose construction comprising, a tubular wall defining a main longitudinally extending passage for conveying a fluid therethrough, said tubular wall having a central longitudinal axis and having a plurality of convolutions therein defined by a continuous longitudinally extending helical convolution, a helical reinforcing member disposed within said helical convolution, and wall means adjoining the exterior of said tubular wall and defining a second longitudinally extending tubular passage for electrical conductor means, said second tubular passage being disposed substantially parallel to said central longitudinal axis, said wall means having a wall portion common with said tubular wall.
Claim 2
Dependent Claim
99 words
A polymeric flexible hose construction comprising, a tubular wall defining a main longitudinally extending passage for conveying a fluid therethrough, said tubular wall having a central longitudinal axis and having a plurality of convolutions therein defined by a continuous longitudinally extending helical convolution, a helical reinforcing member disposed within said helical convolution, and wall means adjoining the exterior of said tubular wall and defining a second longitudinally extending tubular passage for electrical conductor means, said second tubular passage being disposed substantially parallel to said central longitudinal axis, said wall means having a wall portion common with said tubular wall.
Claim 3
Dependent Claim
24 words
A hose construction as set forth in claim 1 in which said reinforcing member comprises a metal wire having a plastic sleeve disposed therearound.
Claim 4
Dependent Claim
24 words
A hose construction as set forth in claim 1 in which said tubular wall and wall means are made as a single piece construction.
Claim 5
Dependent Claim
57 words
A hose construction as set forth in claim 3 in which said wall means defining said second tubular passage comprises a wall of substantially C-shaped cross-sectional configuration defined by a bight having open end edges adjoining said tubular wall along the full length thereof, said common wall portion being disposed between the ends of said C-shaped wall.
Claim 6
Dependent Claim
26 words
A hose construction as set forth in claim 4 in which said tubular wall, C-shaped wall, and common wall portion are of substantially uniform thickness throughout.
Claim 7
Dependent Claim
20 words
A hose construction as set forth in claim 1 and further comprising an electrical conductor disposed within said second passage.
Claim 8
Dependent Claim
22 words
A hose construction as set forth in claim 6 in which said electrical conductor comprises a plurality of electrically insulated metal wires.
Claim 9
Dependent Claim
39 words
A hose construction as set forth in claim 7 in which said second tubular passage has a substantially D-shaped cross-sectional configuration, said D-shaped configuration having an area which is substantially greater than a cross-sectional area through said electrical conductor.
